Description
Compact electrical actuators, especially designed for small two and three way ball valves and
similar drives requiring 90 or 180 degrees of rotation from a single phase or DC. electrical
supply.
The water tight, aluminum alloy housing with steel cover, contains the drive motor and spur
gear box assembly together with the anti-condensation heater and main terminal strip. Two limit
switches provide for position limiting and remote position indication, space is allowed for two
extra switches or a potentiometer for additional position feed back.
